question about PA's load-pull matching

Hi,all
I am a graduate major in RF PA design. I used the cadence spectreRF to sim load-pull matching. I followed the user guide to matching the output of PA. I just wonder how to check the results of my matching if it is correct.
Just like the conjugate matching, when it is well matched that S22 should below -12dB. I wonder if there is a standard like the conjugate matching to check the load-pull matching.
Does anyone can give me some advice?
Thanks a lot!

I don't think a standard exists other than your own specifcations for output power, harmonic levels, efficiency etc. over your frequency of interest. If you meet/optimise your specs, then the load pull matching is complete.
